I am not sure what you mean by "unwrap" ? Are you wanting to project from the circle to a rectangle, interpolating to form a rectangular image like from stretching a sheet?

Use a polar transformation with the center of the transformation set to the center of the circle (roughly [161, 172]).
I like Peter Kovesi's implementation of the polar transformation:
a = imread('http://www.mathworks.com/matlabcentral/answers/uploaded_files/482/crop_image.jpg');
out = polartrans(a,500,500,161,172,'linear','valid');
imshow(out);

What file? Whatever file it is, can't you just click the green triangle? Or type the name of it into the command window?
